i have spring application based on spring batch. default spring batch introduces transaction steps (i.e. @ reader,writer , processor) . there stages don't need transaction enabled. because transaction enabled unnecessary these methods giving me runtime errors making call 2 different databases in 1 method. is there annotation spring provides disable transaction specific set of methods ? or there available in spring batch can allow me rid of transaction either or declarative i open solution can disable transaction globally. link , paper appreciated. in advance samir spring batch inherently transactional. if datasources not transactional, semantics of jobrepository require it. closest can spring batch , not being transactional using resourcelesstransactionmanager. transaction manager no-op transaction manager keeps track of if operation within scope of transaction or not.

i'm making charting application allows create graphs using drag , drop interface. i have highcharts , i'm using highcharts-ng directive. this directive watches title, options, , series. , when person makes change, process them , make changes options object. highcharts-ng redraws chart. the problem i'm finding change few properties in row such options.xaxis , options.yaxis, , whenever application lagging bit because it's launching redraw every change. so angular way approach this, while still being efficient? a potential solution thought of add flag highcharts-ng directive, , have trigger whenever it's changed. , change after i'm done processing data. potential solution listen event inside highchart-ng directive, , trigger redraw whenever event received. these solutions seem/feel bit hacky me. angular own dirty checking , (ideally always, not really) rewrites angular-controlled sections of dom whenever corresponding view models change. th...

i have relatively simple regex problem - need match specific words in string, if entire words or prefix. word boundaries, this: \b(word1|word2|prefix1|prefix2) however, can't use word boundary condition because words may start odd characters, e.g. .999 my solution whitespace or starting token these odd cases.

new programming, may stupid question. if so, apologies. i'm writing class in python on initialization makes request api rather large amount of data: class foo: def __init__(self, params): self.params = json.dumps(params) self.r = requests.get(api, data=self.params).json() after initialization, there bunch of methods — bar , baz — meant, in ideal world, perform different operations on the json fetched upon initialization. when instantiate class , call methods in succession, this: test = foo() test.bar() test.baz() my naive understanding test.bar() , test.baz() performing operations on same json fetched upon instantiation of test , not making own api calls. obviously, whole thing slower if test.bar() , test.baz() each making own requests. understanding correct? or test.bar() , test.baz() fetching own copies of json data? it entirely depends on content of bar , baz functions. could call requests.get if that's how write ...
